Abstract
A light projector is presented including a wireless power coupling mechanism and infra-red communications coupling mechanism which provide a portion of the projector with the capability of complete full-circle rotation about its pan-axis. A stationary base is provided which includes a first transmitter and receiver means for transmitting control signals to and receiving information signals from a second transmitter and receiver means on the rotating portion of the projector. A pan-axis shaft includes the second transmitter and receiver means for transmitting information signals to and receiving control signals from the transmitter-receiver means on the stationary base, and is operative to rotate the rotatable portion of the projector. The infra-red coupling mechanism and wireless power coupling mechanism eliminate the need for hard-wiring between the base and rotating portion of the projector, greatly facilitating continuous and efficient motion thereof.
